We’ve talked to a number of clients over the last month or so who are determined to move away from Autonomy IDOL itself, citing reasons such as a lack of ownership of code (so even tiny changes to a user interface need to be carried out by expensive consultants), scaling being difficult and expensive, and indifferent support even after the HP acquisition. As I wrote at the time moving from one closed-source technology to another doesn’t really reduce any risk that your supplier will change their roadmap, prices or corporate strategy to your disadvantage.
